3. Decals
Excessive vacuum (or pressure) may
damage roof. Use positive aeration
system. Make sure all roof vents are
open and unobstructed. Start roof
fans when supply fans are started.
Do not operate when conditions exist
that may cause roof vent icing.

Roof Damage Warning and Disclaimer
The manufacturer does not warrant any roof damage caused by excessive vacuum or internal
pressure from fans or other air moving systems. Adequate ventilation and/or “makeup air” devices
should be provided for all powered air handling systems. The manufacturer does not reco mmend
the use of downward flow systems (suction). Severe roof damage can result from any block age of
air passages. Running fans during high humidity/cold weather conditions can cause air exhaust
or intake ports to freeze.

* Maximum fuel flow rates listed assume full heat output for gas line sizing purposes. In normal operation, the fuel flow rates
would be substantially lower than indicated, due to actual pressure setting used and cycling of the burner.
** The gas pressures listed show the operating limits for each model heater and are not necessarily the recommended
operating pressure. The actual gas operating pressure should be within these limits, but will vary depending on the type
of grain and the drying system. The maximum setting assumes ideal conditions of relatively low static pressure conditions
with high fan airflow and good quality combustion. High static pressure conditions will require lower maximum gas pressure
setting than specified.

Vertical Profile Angle Configuration
Vertical profile angles have been added to the Downwind Centrifugal Heaters to increase burner
performance quality. These angles have been factory installed with the angle configuration of the smallest
horsepower fan rated for the heater. As a result, some changes will be require d at the time o f installation
once the fan and heater combination is known. This document describes the proper configurations of the
vertical angles inside the heater housing.
Figure 5A
IMPORTANT: Use of the vertical profile angles requires that the upper and lower pro file angles have their
90° bend on the window side of the heater as shown in Figure 5A.

CF-10 Centrifugal Fan and CHD-15 Model Heater
Figure 5B shows the factory configuration. No change is required to the heater.
Retrofit applications require holes to be drilled in the upper and lower profile angles and the vertical angle
to be installed with the noted hardware.

CF-20 Centrifugal Fan and CHD-30 Model Heater
Figure 5C shows the factory configuration for the 20 HP application. Here the long leg of the angle points
toward the center of the heater to provide a 17" wide opening across the housing at the location of the
angles. No change is required to the heater.
Retrofit applications require holes to be drilled in the upper and lower profile angles and the vertical profile
angles to be installed with the noted hardware.

Always disconnect and lock out power before working on or around heater.
CF-25 Centrifugal Fan and CHD-30 Model Heater
Figure 5D shows the configuration for the 25 HP application. The vertical profile angles must be
repositioned. Flip each angle end for end and install it with the short leg of the angle pointing toward the
center of the heater. This provides a 19-1/2" wide opening across the heater housing at the location of
the angles.
Retrofit applications require holes to be drilled in the upper and lower profile angles and the vertical profile
angles to be installed with the noted hardware.

Deluxe Heater Electrical Installation
DANGER
Standard electrical safety practices and codes should be used when working with a heater. Refer to the
National Electric Code Standard handbook by the National Fire Protection Association. A qualified
electrician should make all wiring installations.
